User registered multiple times

Note: As of July 9, 2018, Blackbaud's School Management solutions (which include Core, onBoard, onCampus, onMessage, and onRecord) are utilizing a new top level navigation. This primarily affects users performing administrative tasks-constituent navigation for most parents, students, faculty, and alumni will remain the same. We appreciate your patience as we work to update our documentation. If you are seeing this message, the content of this solution is still being vetted for possible updates. Please refer to this mapping document if you need assistance finding a task in the new navigation.

When working with an event registration, you may notice that some users have registered multiple times, even though the box is not marked to allow Authenticated users to register multiple times.

If your form is public, meaning that people can register without logging in, the system cannot differentiate between registries, and therefore cannot detect multiple registries. This can only be prevented by securing the form and requiring users to login to fill out the form.
